The Highways Agency has been advised that one lane of the northbound - Ie Chester-bound - A483 on its approach to the roundabout with the A55 will close from 8.30am until 4.30pm for Scottish Power to carry out works.
The lane closure is in addition to the current capacity restrictions at the roundabout itself as the Highways Agency delivers a £5.3 million Pinch Project to tackle congestion and boost safety.
Drivers are advised to leave extra time for their journeys and check traffic conditions before setting out.
